josh_c: I'll give you my 2 cents worth on the subject, I have both Turbo & Standard Plug engines (RB Concepts) in which I run in my Buggys & Truggies, I don't dislike either, but the Turbo Plug is supposed to give you up to 10% more power & in my opinion gets better fuel mileage, but sometimes they are a little more difficult to get started & mine seems to take just a bit longer to warm up but when it does, it's Awesome. I'm not sure if you're planning on putting it in a Buggy or Truggy, as I run a Standard Plug WS7 III in my 777 WC & a Turbo Plug C6 BB7T Big Bang in my Truggy!
